完形填空(共20小题;每小题1分,满分20分)

When someone has deeply hurt you, it can be extremely difficult to let go of your anger. But forgiveness is possible—and it can be surprisingly    16    to your physical and    17    health.

“People who always forgive others   18    less depression, anger and stress and more hopefulness,” says Frederic Luskin, Ph.D., the    19    of Forgive for Good. “So it can help    20    on the wear and tear on our organs, reduce the wearing out of the immune(免疫的) system and    21    people to feel more vital.”

So how do you start the forgiveness? Try    22    these steps:

Calm yourself. To defuse your    23   , try a simple stress-management technique. “Take a couple of breaths and think of    24    that gives you pleasure: a   25    scene in nature, someone you love,” Luskin says.

Don’t    26    an apology. “Many times the person who hurt you has no    27    of apologizing,” Luskin says. “They may have wanted to hurt you or they just don’t see things the same    28   . So if you wait for people to apologize you could be waiting a(n)   29    long time.” Keep in mind that forgiveness does not necessarily mean    30    to the person who upsets you.

Take the control away from your offender. Mentally replaying(重播) your    31    gives power to the person who caused you pain. “   32    focusing on your hurt feelings, learn to look for the love, beauty and kindness   33    you,” Luskin says.

Try to see things from the other person’s view. If you empathize(把感情移入) with that person, you may    34    that he or she was acting out of ignorance, fear—even love.

Recognize the benefits of forgiveness. Research has shown that people who always forgive others will get more energy, better    35    and better sleep.

Don’t forget to forgive yourself.“For some people, forgiving themselves is the biggest challenge,” Luskin says. But it can rob you of your self-confidence if you don’t do it.”

A Charlotte, N.C., man was charged with first-degree murder of a 79-year-old woman whom police said he scared to death. In an attempt to evade policemen after a bank robbery, the Associated Press reports that 20-year-old Larry Whitfield broke into the home of Mary Parnell. Police say he didn’t touch Parnell but that she died after suffering a heart attack that was caused by terror. Can the guy be held responsible for the woman’s death? Prosecutors(公诉人) said that he can under the state’s murder rule, which allows someone to be charged with murder if he or she causes another person’s death while committing or fleeing from a severe crime like robbery—even if he or she doesn’t kill someone on purpose.

But, medically speaking, can someone actually be frightened to death? We asked Martin Samuels, chairman of the neurology department at Brigham and Women’s Hospital in Boston.

Absolutely, no question about it.

The body has a natural protective method called the fight-or-flight response(战或逃反应), which was originally described by Walter Cannon,the chairman of Harvard University’s physiology department from 1906 to 1942. If, in the wild, an animal is faced with a life-threatening situation, the autonomic nervous system responds by increasing heart rate, increasing blood flow to the muscles, and slowing digestion, among other things. All of this increases the chances of succeeding in a fight or running away from an aggressive beast. This process certainly would be of help to primitive humans. However, in the modern world there is obvious decline of the fight-or-flight response.

The autonomic nervous system uses the chemical messenger to send signals to various parts of the body to activate the fight-or-flight response. This chemical is toxic in large amounts; it damages the organs such as the heart, lungs, liver and kidneys. It is believed that almost all sudden deaths are caused by damage to the heart. There is almost no other organ that would fail so fast as to cause sudden death. Kidney failure, liver failure, those things don’t kill you suddenly.

By the way, any strong positive or negative emotions such as happiness or sadness can cause the same result. There are people who have died in intercourse or in religious passion. There was a case of a golfer who hit a hole in one, turned to his partner and said, “I can die now”, and then he dropped dead. For about seven days after the 9/11 terrorist attacks on the World Trade Center and Pentagon there was an increase of sudden cardiac death among New Yorkers.

Why the Charlotte, N.C., man was charged?

A. Because he threatened the policemen to kill an old woman.

B. Because he caused an old woman’s terror and she died.

C. Because he beat an old woman and caused her heart attack

D. Because he murdered an old woman while robbing a bank.

Which of the following about the fight-or-flight response is true?

A. The fight-or-flight response was raised and proved by Martin A. Samuels.

B. It is a natural protective method that can’t be found in all creatures but humans.

C. The ancient humans had a superior fight-or-flight response than modern ones.

D. The fight-or-flight response is beneficial to both our actions and organs.

What activity can we infer is less likely to damage the organs?

A. Winning a big lottery.                   B. Missing a dead family.

C. Watching a horror movie.                 D. Listening to a sweet song.

The purpose of the passage is_________.

A. to explain why people will die of a heart attack

B. to offer some advice on protecting us from heart failure

C. to compare different kinds of feelings to cause a death

D. to show strong emotions can cause a sudden death

At one time or another most farmers have problems with mice. This is especially true for grain farmers. Mice eat a lot of grain. They also carry diseases(疾病), which people can get from eating or touching grain the mice have made dirty. Farmers can use special grain storage building or they can kill the mice. However, both methods can be costly. Farmers must buy materials to build the special grain storage buildings or chemical poisons to kill the mice.
Here is a way to kill mice without spending a lot of money. It is a simple but effective king of mouse trap. The method is first used by some farmers in the west African country of Mali. An agricultural expert in Mali reported about the Mali mouse trap in a magazine. The expert reported that his gardener caught 150 mice in just one night. The gardener used four traps. The trap is easy to make. First, remove the top from a 20 liter metal or plastic container(容器). Put it n a hole in the ground. The top edge of the container should be the level with the surface of the ground. Fill the container with water to within eight centimeters of the top. Add tiny pieces of grain wastes. They should float on the water. Also put some wastes on the ground near the trap. During the night, mice will come out to eat the grain wastes. They will fall into the container and drown. Replace the food in the trap every night.
56. According to the passage,       used the mouse trap first.
A. an agricultural expert in the west Africa      B. farmers in the United States
C. an American gardener                    D. farmers in Mali
57. What does the passage mainly tell us?
A. A simple and effective method used by farmers to kill mice.
B. Methods used by farmers to kill mice.
C. Farmers have problems with mice.
D. How to kill mice.
58.      is not needed in making the mouse trap.
A. Water                            B. A container
C. chemical poison                    D. Food
59. Which of the following can’t protect grain from being eaten by mice?
A. A special grain storage building.          B. Chemical poisons.
C. A mouse trap.                        D. A hole in the ground.
